This mine was the longest continuously operating mine in the Cobalt area (1905-1967). It was developed through 5 shafts, the deepest being 345ft; and over 16 miles of drifts, cross-cuts, and raises. Total production was approx. 41 million oz. Ag; 3 million lbs. Co; 200,000 lbs. Ni; 500,000 lbs. Cu; and 64 oz. of gold.
